"THE BEER-WARE LICENSE" (Revision 43):

As long as you retain this notice you can do whatever you want with
this stuff. If we meet some day, and you think this stuff is worth it,
you can buy me a non alcohol-free beer in return.

If a project uses a different license it is mentioned in the
project itself.
